Pyranometers

Beeservices  offers two types of pyranometers; our original silicon-cell models and our new line of thermopile pyranometers, both of which are now ISO 9060:2018 Class C rated (previously known as second class). Silicon-cell solar radiation sensor models are excellent for applications that do not require the higher accuracy and cost of a thermopile pyranometer. They are less expensive and have a faster response time, but have higher errors under cloudy conditions. Our new cost-effective thermopile pyranometers features a blackbody thermopile detector that provides a much broader and more uniform spectral response for better performance in all atmospheric conditions that compares favorably to other thermopile pyranometers at a fraction of the cost. Applications include shortwave radiation measurement in agricultural, ecological, and hydrological weather networks, measurement of global solar radiation, and optimizing photovoltaic systems.
